A Laserator LARGY-OTF on-the-floor fiber laser marking machine is operated on the floor. It has a 80cm long Z axis on which a specifically designed scan head is moved up and down vertically based on the programs created. This fiber laser is a CLASS-I laser marking machine. It does not mark if the front door is not completely closed. Instead of a 2D scan head, a 3D scan head designed by our engineers can be integrated into a LARGY-OTF. A Laserator LARGY-OTF fiber laser marking & engraving machine is powered up with our " smt-series Laserator 20, 30, 50, 60, 70, 100 & 120W fiber laser engines".
